GAS B RNER.

Application filed March 8, 1920, Serial No. 363,986. Renewed June 26, 1922. Serial No. 570,935.

To all whom it may concern:

Be it known that 1, WILLIAM J. BARBER, a citizen ofthe United States, residingat Cieveland in the county 01 Cuyahoga and State of Ohio, have invented certain new and fuseiful Improvements in Gas. Burners, of

which the following is a specification.

My invention pertains to an improvement in gas burners, and my present object is to provide a burner adapted to promote uniform COHlbUSlJlOIl over an extensive area of finely-Woven wire screen. To accomplish the desired result I provide. means for dis charging gas on diverging lines and in a circle against a deflector which is adapted to spread the gas laterally into an annular gas distributing chamber having additional means therein to diffuse and spread a combustible mixture beneath the bottom of the screen. i y

In the drawing accompanying this application, Fig. 1 is a plan view of the burner with a portion 01 the screen and clamping rin broken away. Fig. 2 is a vertical sec tion centrally through the burner- Fig, 3 is a perspective view of the clamping ring. Fig. a is a cross section of the burner screen. Fig. 5 is a perspective view of the spreader disk. Fig. 6 is a side elevation, partly in section, of the burner body, and Fig. 7 is a side view of the gas nipple or supply connection.

The present gas burner is especially designed for use in domestic cooking stoves or ranges having open grids upon which a pan or other cooking utensil is adapted to rest. To provide an effective body of flame beneath the larger utensils the burner must be constructed to spread or todifi'use the flame over an area approximately 4: to 6 inches in diameter. To obtain an effective and wide spreading flame with a woven-wire screen I have found it necessary to provide special means within the burner to diffuse the combustible mixture.

Thus, the burner comprises a round flat body 2 having a shallow annular chamber 3 on its upper side and a tubular extension 41 at its bottom side which is adapted to proprovide a mixing chamber 5 for gas and air. The gas is discharged upwardly through a nipple or gas supply connection 6 which is screwed centrally into the closed bottom end of extension l and the air is entrained through openings 7 in the side wall of extension e at points adjacent the discharge end ot the nipple. A plug 8 wedged withinthe upper end of the nipple or tube 6 has a central orifice of relatively small diameter through which the gas is discharged and the plug is drilled or otherwise formed with an elongated tapering entrance 9 and a shallow flaring outlet 10 on opposite sides of the orifice 8, whereby in operation the gas is caused to issue on diverging lines and in a circle upwardly through mixing chamber 5. Attention is called in this connection to my appli-, cation Ser. No 368,984, filed March 8, 1920,

in which the subject matter of the tube 6 and nipple 8 is claimed. The angle of discharge may be varied by slight changes in the forms ation of the gas passage in plug 8, but in a burner having the proportions substantially as shown in the drawings, the diverging line of travelof the gas through mixing chamber 5 will causethe gas to pass through the upper mouth of the chamber in close proximity to the corner edge 11 thereof, and by placing a spreader plate or disk 12 opposite said mouth and at a slight distance above or apart from the bottom of chamber 3 the gas will strike the bottom side of plate 12 and thence the gas will be deflected latorally into chamber 3 where it will rise and be discharged through the multitude of fine openings in the burner screen 12 which completely covers the top of shallowchamber 3. This screen is made of finely-woven wire to provide openings or interstices small enough to prevent back-firing, and in a burner having a chamber 8 or" extended width or diameter the gas or combustible mixture tends,

to pass through the burner screen in segregated areas usually in the form of a ring which isnot coextensive with the full width of the screen between the edge of the disk 12 and the outer annular flange 13 of body 2. To overcome this diverse or uneven disthe screen between disk 12 and body flange 13. In eflect rib 14L acts as a bafiie and diffusing member for the gas and combustible inner central portion of the screen adjacent.

the circumference of the deflector disk as well as being deflected outwardly toward and to the extreme outer diameter of the screen adj acentbody wall 13, and in practice the entire bottom area of the screen is traversedby the mixture and passes upwardly through the. screen through all the interstices or meshes to promote uniform combustion outside and in close proximity to the screen over the entirercircular area between the borders of the burner and the central disk12'. The flame is vari-colored-green, violet and: blue, tinged with orange, and burns in the form ofa wide ring above the screen and at a high degree of temperature. Varying-pressures on the gas supply do not appear to materially effect combustion except to raise and-lower the flame, and a more intense heat is obtained with this burner than with the other burners in common use in cook stoves and ranges.

Notwithstanding the high temperatures derived bythis burner I find that the screen is notmaterially affected by the heat but that the screen when made of the proper material has a long life. However, as the openings and interstices are necessarily fine and small thescreenvis apt to become clogged when a cooking utensil is tipped over or overboiling occurs'with certain materials, and therefore the burnerscreen is removably clamped in place upon the burner body by a separate ring 16 andscrews 17 to facilitate removal and cleansing of the screen. The screen also rests, atits center upon disk 12 and is held under suiiicient tension by the clamping ring 16 to prevent it from warping or buckling, I'prefer also to make the spreader plate or deflector disk 12 a separate removable member having notched feet 18 adapted to hold the plate or disk centrally in place upon the body opposite the, mouth of mixing chamber 5.

What I claim is:

1. A gas burner, having a shallow distributing member for a combustible mixture, a woven wire burner screen forming one wall of said chamber open into said distributing chamber, a deflecting member within said distributing chamber opposite said mixing chamber, means to discharge gas into said mixing chamber against said deflecting member, and means Vltlllll said; distributing chamber to diffuse the combustiblemixture uniformly beneath said screen.

2-. A gas burner, comprising a chambered body having a mixing chamber at its bot tom provided with a gas supply connection, a deflector member mounted opposite said gas supply connection, awoven wire screen removably mounted upon said body and deflector member and an annular gas diffusing rib within said body beneath the screen adjacent said deflector member;

3. A gas burner, com-prising'a round bodyv having a shallow chamber in its top and a tubular extensionat-its bottom and provided with an annular rib within the bottom side of said chamber, a removable screen mounted upon said body forming one wall of said chamber, a gas deflecting disk seated centrally beneath said screen within said chamber opposite said tubular extension, and a gas discharge nipple centrally seated within said extension and adapted to discharge gas on diverging lines in a circle against said deflector disk;

Signed at Cleveland, in the county of Cuyahoga, and State of Ohio, this 1st day of March, 1920.
